Diagnostic Features	Test large, depressed with deep anterior sulcus Apical disc slightly posterior; ethmolytic with three gonopores Ambulacrum III non-petaloid, deeply sunken on aboral surface; pores small and rudimentary in groove Petals narrow with narrow perradial zone; anterior petals longer than posterior petals Peristome close to anterior border and largely hidden by labral projection. Labral plate short, not extending beyond the first adjacent ambulacral plate; sternal plates isometric peripetalous fasciole well developed; strongly indented behind the anterior petals. No other fascioles present

Species Included	L. lamberti (Sanchez Roig, 1924); early Eocene, Cuba L. lyoni (Hutton); Oligocene, New Zealand L. perplexa Henderson 1975, Miocene, New Zealand L. perdita Henderson, 1975; Tertiary, New Zealand
Classification and/or Status	Spatangoida, Paleopneustina, Schizasteridae?
Remarks	Kier (1984) revised this genus on the basis of the type species and demonstrated that it had only a peripetalous fasciole. Despite this he argued that it was a Schizasterid that had lost its latero-anal fasciole, like Abatus. Sanchez Roig, M. 1953. Dos nuevos generos de Equinoides cubanos: Lambertona y Neopatagus.
